I use the System.Net.Mail namespace to send email messages in my application and I have a beta customer that reported that some characters were not coming through correctly on his CZECH box. I was not currently giving the option to the user to select an encoding, but I think that I actually should be.

This has worked for over one or two years. Today I realized upon testing I get the following error:The procedure entry point IstrcmpiI could not be located in the dynamic link library MSDART.DLL.Upon some research I found that maybe I needed to install MDAC 2.8, which i downloaded and installed today, however i still get the same error. I have had my communications and network admins check traffic and connectivity to the smtp server and all is working fine. Yet I still get the error.
I am teaching myself vb.net and wanted to change this code to have an embedded mail.boby from a text file instead of the file attachment. Code spippet below and where I need help is mail.Body = ("tracertALL.txt")
that just puts the name of the file NOT the contents of the file. This code is a CMDWrapper that runs a batch file and I want the contents of a trace route that is pipe to a file >> tracertALL.txt .

Sending email in .NET through Gmail

I am a one man dev shop and need some outside opinions on how to approach this project.
I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?

I am making a program that would allow the user to send me feedback directly from the program I have a user's Experience log. I need a way for the user to send me a mail without him knowing my email address and also attaching the user's experience log (a text file) as an attachment in the mail sent to me. Is there a way to send this email to me with the attachment. I am using vb.net 2010 on framework 3.5.
View 7 RepliesFor the life of me, I cannot figure out how to show the From Name in an email.I've seen people guess like this:
mm.To.Add("bsmith@email.com", "Bob Smith")
but that doesn't work...
This works:
Dim mm As New MailMessage("from@emailaddress.com", "to@emailaddress.com")
This doesn't:
Dim mm As New MailMessage("from@emailaddress.com", "to@emailaddress.com;metoo@emailaddress.com")

I am trying to learn a little more about reading and writing Outlook mail messages. So I've written a small app to read my mail messages and pull certain lines from the body. When I run the app I get to a certain point and start getting error messages telling me I have a limit on the number of messages I can have open. With that I figured something is not closing properly. All of the examples I've checked out (I've been at this most of the morning) I've not seen one thing where the code is closing the message after it's been read. I've included the code and as you can tell there's not much to it.

Automagically enter the distribution name in the To field and PersonA, PersonB in the CC field, the Subject and the Body all prefilled and, hopefully the user's signiture so that all the user has to do is click on send?

I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works.

I posted the following description before and the only suggestion that I received was to switch to System.Net.Mail code. I did switch and I continue to get the same randow and intermittent error.
Problem: Failure of in-house written VBScript that runs from a web page which calls CDO library to send an SMTP message.
Systems: About 100 Windows XP, Professional, Version 2002, SP2 clients using IE6 and IE7. Symantec 10.1.6.6010. All Microsoft patches are regularly installed.
Symptoms: Web application has sent messages for years without error. About December 2007 an intermittent failure began. About 5% of the SMTP messages are not being sent.
Research 1: Added code to trap error and got error number -2147220973 and error description, "The transport failed to connect to the server".
Research 2: Verified that the failed messages were not leaving the client by using a hardware network sniffer.
Research 3: Used SysInternals/ TCPView to monitor while sending messages.It didn't always show when a message was sent.Perhaps it needs to operate at a lower speed than 1 second. When TCPView did show something it was that ccApp.exe,Symantec antivirus,was communicating with the SMTP server.
Research 4: Reviewed all tools available in Sysinternals but didn't find any way to monitor the messages better than TCPView.
Research 5: Placed error checks throughout the code and proved that the error is in the iMsg.Send command.
Set iMsg = CreateObject("CDO.Message")
iMsg.Send

I want to use System.Net.Mail.SendAync in an ASP.NET MVC2 application. I see that it throws an InvalidOperationException if there is already a SendAsync call in progress. Does this mean only one SendAsync is allowed per host, or per thread? For example, if I simultaneously have 2 web users from 2 different remote hosts, can each use SendAsync at the same time?

In ASP.NET, I can just put my mailSettings in web.config and then ystem.Net.Mail.SmtpClient's default constructor will read them. In a regular VB.NETroject, not ASP.NET, I thought I could just put mailSettings in app.config. HoweverSmtpClient() doesn't appear to read settings from app.config. Is there a step I'm missing in order to tell a VB.NET application to read from app.config?
